Specification of Letters Patent.

Patented Au 27,1912.

Application filed October 1'9, 1911. Serial no. 655,557.

To all whom it may concern Be it knownthat I, GUSTAV KANTER, a subjectof the Emperor of Germany and King of Prussia, and a resident ofHamilton street, in the post-town of Murtoa, in the county of Borung,State of Victoria, Coinmonwealt-h of Australia, have inventedcertain-new and useful Improvements in or Relating to PneumaticShock-Absorbers for Vehicles, of which the following is a specification.2

This invention relates to pneumatic shock absorbing devices interposedbetween the ve hicle body and the wheels thereof and preventing theconveyance of road or other shocks from the wheels to the said body.

The object of the invention-is to provide a device particularly for usein con unction with an automatic pneumatic vehicle wheel,

such as that disclosed in concurrent application tor patent filed priorhereto :by the presentapplicant. By the invention astorage reservoir 1sprovided for surplus air pumped by the vehicle wheels which air whenexcessive in the reservoir may be led therefrom and utilized for anyother purposes desired- -But in order that this in vention may be betterunderstood reference will now be made to the accompanying sheet. ofdrawings which is to betalien as part of this specification and readherewith z- Figure 1 is a sectional view of this invention receiving airthrough a dead or fixed axle. Fig. 2 is a sectional view of thisinventlon receivlng air through a l1ve or revoluble axle. Fig. 31s aview of a collapse preventer.

=4: and amp leather 38. above the baseplate is an inner collar 5' Thisinvention includes a'casinghaving a base plate 2 upstanding abovewhichis anouter collar 3 provided with piston rings Also upstandinghavingair outlet passages .6 formed therein,

each controlled by a non-return valve 7. VVithi'n the inner collar 5 isa minor cover 8 provided wit-h piston rings 9 and a cup leather 391andalso having in its top a depression or saucer 10. Upstanding fromthe-minor cover S are a plurality of studs l0 around each of which is aminor cushioning spring 41. Around the outer collar 3 is a major cover11 having at or near" its top apivot pin 12 mounted lug .13. At thetopof the major cover 11 is a lubricating cup 14 from which passes aminor vertical lubricating passage 15. A lubricant drips within theinner chamber.

from this assa 'e into the saucer 10. Also Formed by the outer collar 3and the 0 major cover 11 between the inner collar' 5 and the mmor cover8 is an outer chamber.

Formed in the outer collar 3 are oulet passages 44 each controlled by anon-return valve 45. with the outer chamber. Formed by the inner collar5 and minor cover 8, and within the same is an. inner chamber.Upstanding within the inner chamber is a pillar 42 on the top of whichreposes a non-return inlet vhlve 17. This controls a. delivery port 18in the said pillar. Communicating with the delivery port IS, when(Fig. 1) a dead axle such as 19 is used, is an axle delivery port 20.Supported by the pillar 42 is also a major cushioning spring 43. Anynumber of pillars and springs 43 may be used.

When a live axle (Fig. 2) such as 21 is used a collar 22 is providedthereon. Around said axle in the said collar is formed an annular groove23 with whichcommunicate subsidiary radial ports 24. These communicatewith .a major delivery port 25in the axle. Then a live axle is usedthere is also provided upon the outer collar 3 a subsidiary collar 28provided with an annular groove lonnnunicat-ing with the groove 26 is adelivery port 27 which conveys air from the groove to the delivery portin the pillar In addition to the foregoing with motor or like vehiclesthere may be pivoted to any suitable part of the vehicle by a pivot pin29, a lever 80 locked in any desired position The said passagescommunicate in any well known way. Should four absci-hers be used, twoabove the front axle and two above the back axle of a vehicle, (althoughany number may be used) the said lever 30 may be pivoted in closeproximity to the drivers seat. A lever 31 is then pivoted by a pivot pin32. to any suitable part of the vehicle near the rear thereof.Connecting the levers 30 and 31 is a link 33 having near its front end adepending portion'3 l'from which projects a finger 35.

'Protruding from the lower end of the lever 31 is an elbow 36 having afoot 37. Upon a vehicle stopping the driver by the'lever 80 causes thefinger 85 to en age the front axle of the vehicle or a protu erance 46project- 110 lug therefrom while the elbow 36 engages the rear axle or aprotuberance 47 projecting 3 escapes by the non-return valves 45. Thiscranked and provided with, a depending portion and finger. Upon thedriver wish- 5 mg to start the vehicle the lever 30 is again operateddisengaging the finger 35- and elbow 36, which permits the vehicle bodyand the major cover or covers 11 to descend forcing air from the outerchamber. This air may be utilized to start the engine.

I With this invention the vehicle body may be supported'by the pin 12and air is admitted to'the absorber from the axle whether it be a liveaxle or a dead axle, into the inner chamber. Upon a predeterminedpressure being reached air escapes from the inner chamber into the outerchamber. case the covers 8 and 11 are elevated to a greater or lesserextent. 'Upon a shock bemg communicatedto the absorber the covers riseor fall around the inner and outer collars 3 and 5. When a predeterminedpressure is reached in the outer chamber either through an over suppl orbyreason of the rising and falling oft e outer cover 11, air

air may e directed where and as desired and used for any purpose, Itmaybe heated and expanded, used for ower, assimilated I 3 0 with Oll,spirits or -the li e and used as an aj lluminative, or be utilized inother ways such as for sounding an alarm signal.

.' .JWhile the inner chamber is belng' filledwith air theminor coverrests upon the majo'r cushioningspring s and the major cover upon theminor cushioning springs.

Having now described my invention, what I claim as new antkdesire tosecure by Letters Patent is:

1. In; improvements in or relating to pneumatic shock absorbers {orvehicles, a casing consisting of'an outer collar and an inner collar, amlnor-cover moving vertically in relation. to the said inner collar anda major cover moving vertically in relation to theouter' collar, saldminor and major .cov-' ers being relatively movable.
